TIA-942 Data Center Cabling Standard Amended

TIA TR-42 Telecommunications Cabling Systems engineering committee recently released a second addendum to the TIA-942 Data Centers standard. The Addendum, titled Telecommunications Infrastructure Standard for Data Centers Addendum 2-Additional Guidelines for Data Centers, specifies revised requirements for temperature and humidity in data centers. The addition was made to harmonize the standards with environmental guidelines developed by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). The revised requirements should reduce energy consumption for heating, ventilation, and air conditioning; and should provide more flexibility in maintaining temperature and humidity in data centers.

The Addendum also amends the cabling types recognized to include and recommend augmented category 6 (category 6A), provides additional guidelines regarding the use of transmission equipment in data centers, and provides revisions to Annex G Tiering Reference Guide.
